Steel Mills Use Manganese: The most important use of manganese is in the manufacturing of steel. Manganese gives the steel strength and hardness. Without manganese, the steel used to make armor plate, crusher jaws, and impact tools would not be as durable. Image Â© iStockphoto / Huyangshu.
Manganese is too brittle to be of much use as a pure metal. It is mainly used in alloys, such as steel. Steel contains about 1% manganese, to increase the strength and also improve workability and resistance to wear. Manganese steel contains about 13% manganese. This is extremely strong and is used for railway tracks, safes, rifle barrels and prison bars.
